> do you link the bttv driver into the kernel or load it as a module?
Now for the longer answer :-), copied to the list as well.
You want to configure the kernel if you're building on to support the
kernel module loader. Then you can put this in /etc/conf.modules:
alias char-major-81 bttv
This makes the kernel load the bttv module and all of the modules it needs
on the first access of device #81 (/dev/video*).
You may need to create the devices with
but I think they might be there in 6.1.
You'll need to copy the device .o's out of the bttv driver directory into
/lib/modules/<kernel-version>/misc, overwriting any that might have been
there from the RH distributed bttv.
You'll need to reboot, I think, to have the conf.modules method work. You
can try by hand what the kernel is doing with
Run dmesg to see what happens. This is what I see on my machine:
Linux video capture interface: v0.01 ALPHA
bttv0: Brooktree Bt878 (rev 2) bus: 0, devfn: 136, irq: 9, memory: 0xf4001000.
